In reply to MaranaF: There were a few posts about the figfour a while back. I enjoy using them, makes a trip to the wall a bit less monotonous

I did find walls weren't interested in setting routes for them and for me locally undercover rock was the only one to allow there use, haven't asked at redpoint. At lot of walls probably aren't happy with the added potentially risk with them. Although alpkit provide a full H&S risk assessment for their use for climbing walls.

Rokt have one of their silos dedicated to Figfour, at least they did the last time I was there. I know that they have been used at The Westway, The Castle, Nottingham Climbing Centre, The Cragg, Indy, Dynamic Rock, Foundry, Dart Rock, Redpoint, The Beacon, Undercover Rock.. that list is not definitive but its a start.
